WASHB OILER.

Specification of Letters Patent.

llatented June 2, 1914.

Application filed May 28, 1913. Serial No. 770,415.

To all whom it may concern Be it known that l, JOHN H. MoCUNn, a citizen of the United States, residing at Kaw city, in the county of Kay and State of Oklahoma, have invented new and useful Improvements in ll ashboilers, of which the following is a specification.

This invention is an improved wash boiler, the objectof the invention being to provide an improved wash boiler which embodies a bottom, a perforated semi-tubular false bottom having its edges secured to the bottom, a water heating coil arranged below the bottom and connected at its ends to the bottom at points under the false bottom, and further provided with upwardly projecting tubular arms connected to the per forated false bottom and having openings in their sides to discharge jets of hot water laterally into the vessel, the perforated semitubular false bottom acting to discharge jets of hot water upwardly in the boiler, the invention consisting in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a plan of a wash boiler constructed in accordance with my invention with one of the vertical tubular arms shown in section. 2 is an inverted plan of the same, showing the arrangement of the water heating coil. Fig. 3 is a vertical sectional view on the plane indicated by the line A--A of Fig. 1. Fig. i is a similar view on the plane indicated by the line BB of Fig. 1.

My improved washer or wash boiler is here shown as rectangular in form and coinprisiug a bottom 1 and side walls 2. Two of the side walls are provided at points intermediate their ends with handles 3. The boiler is preferably made of sheet metal. Under the boiler is a water superheating coil 4t which, is preferably of the form here shown and is provided at its ends with upwardly extending elbows 5 having nipples 6 attached thereto which extend through and project above openings in the bottom of the boiler near diagonally opposite corners thereof, locking nuts 7 and washers 8 being also provided to securely fasten the nipples and, hence, the ends of the coil to the bottom of the boiler. A false bottom 9 is arranged on the bottom of the boiler on the inner side thereof and is here shown as comprising a pair of U-shaped substantially semi-tuloular connected members 10 which are perforated as at 11 and the edges of which are soldered or otherwise secured to the bottom of the boiler. The ends of these false bottom members 10 are arranged over the ends of the coil where the latter are connected to and extend through the bottom of the boiler so that the coil communicates with the boiler at points under the false bottom. Each of the U-shaped perforated semi-tubular members has a long arm and a shorter arm. The shorter arms of said members are arranged opposite each other and near the center of the vessel and are connected together. il ubular arms 12 pro" ject upwardly from the members of the false bottom, have their upper ends closed and are provided with perforations 13 in their sides, these tubular arms being arranged at different points in the boiler, near its corners and at its center.

VVhen the boiler is in use, on a stove or other heater, water is heated in the coil as well as in the boiler andthe heated water in the coil by expansion forces its way up into the boiler under the false bottom members, upwardly from the latter through the openings therein in jets through the clothes in the boiler and also in lateral jets through the clothes in the boiler fronthe perforations in the vertical tubular arms. Hence, the water in the boiler is caused to keep in circulation and such movement of the water in addition to the action of the jets pro duced by the false bottom and heating coil causes the clothes to be rapidly and thoroughly cleansed. By the arrangement and construction of the pair of tl-shaped perforated semitubular members, perforations are provided at all points on the bottom of the boiler so that at points where the water is hottest and there can be a flow from the coil to the interior of the boiler and the points where the temperature is not so high and can be returned from the boiler back to the coil.

While I have herein shown and described a preferred form of the invention, I would have it understood that changes may be made in the form, proportion and construction of the several parts without departing from the spirit of the invention and within the scope of the appended claim.

I claim The herein described wash boiler comprising a vessel. having a bottom, a false bottom in the vessel and comprising a pair of U-shaped perforated semi-tubular members each having a long arm and a shorter arm, the shorter arms of said members being arranged opposite each other, a connecting member between said shorter arms, said members having their edges secured to the bottom, a Water heating coil arranged be- 10W the bottom and connected at its ends to the bottom at points under the terminal portions of the longer arms of the false bottom members and tubular perforated arms extending upwardly from the members of the false bottom and having their upper ends closed.

In testimony whereof I affix my signature in presence of two Witnesses.
